Defensive publication

ABSTRACT

A METHOD OF SECURING STACKED SUBSTANTIALLY RIGID, SELFSUPPORTING POLYOLEFIN CONTAINERS SUCH AS PAILS, BOTTLES AND THE LIKE AGAINST SLIPPAGE COMPRISING APPLYING A LACQUER COATING TO ADJACENT CONTACTING PORTIONS, SUCH AS CONTACTING OUTER RIMS OF SUCH CONTAINERS, SAID LACQUER COATING CONSISTING ESSENTIALLY OF AN ORGANIC SOLVENT, SUCH AS THE AROMATIC HYDROCARBONS TOLUENE AND XYLENE OR CHLORINATED ALIPHATIC HYDROCARBONS SUCH AS TRICHLOROETHYLENE AND KETONES SUCH AS METHYL ETHYL KETONE, HAVING DISSOLVED OR DISPERSED THEREIN A SUBSTANTIALLY LINEAR CHLORINATED POLYETHYLENE WHICH CONTAINS FROM ABOUT 25 TO 50 AND PREFERABLY FROM ABOUT 36 TO 48 WEIGHT PERCENT OF CHEMICALY COMBINED CHLORINE AND HAS A RELATIVE CRYSTALLINITY OF BETWEEN ABOUT 15 AND 28 PERCENT WHEN CONTAINING ABOUT 25 WEIGHT PERCENT CHLORINE AND A RELATIVE CRYSTALLINITY OF LESS THAN ABOUT 10 PERCENT WHEN CONTAINING ABOUT 34 WEIGHT PERCENT CHLORINE; WHEREIN THE DRIED RESIDUE OF THE LACQUER COATING PROVIDES A SLIP ANGLE BETWEEN THE ADJACENT CONTACTING SURFACES OF SUCH CONTAINERS OF BETWEEN ABOUT 10 AND 50 DEGREES, SUCH SLIP ANGLE BEING DETERMINED BY RAISING ONE END OF THE PLATFORM ON WHICH SUCH CONTAINERS ARE SUPPORTED AND DETERMINING THE ANGLE FROM THE HORIZONTAL WHEN THE UPPERMOST CONTAINER COMMENCES TO SLIDE OR MOVE.

C08f 3/ 22 U.S. Cl. 117-94 No Drawing. 5 PagesSpecification A method of securing stacked substantially rigid,selfsupporting polyolcfin containers such as pails, bottles and the likeagainst slippage comprising applying a lacquer coating to adjacentcontacting portions, such as contacting outer rims of such containers,said lacquer coating consisting essentially of an organic solvent, suchas the aromatic hydrocarbons toluene and xylene or chlorinated aliphatichydrocarbons such as trichloroethylcne and kctones such as methyl ethylketonc, having dissolved or dispersed therein a substantially linearchlorinated polyethylene which contains from about 25 to 50 andpreferably 'from about 36 to 48 weight percent of chemically combinedchlorine and has a relative crystalllnity of between about and 28percent when containing about weight percent chlorine and a relativecrystallinity of less than about 10 percent when containing about 34weight percent chlorine; wherein the dried residue of the lacquercoating provides a slip angle between the adjacent contacting surfacesof such containers of between about 10 and 50 degrees, such slip anglebeing determined by raising one end of the platform on which suchcontainers are supported and determining the angle from the horizontalwhen the uppermost container commences to slide or move.
